This invention relates to improved water likean arrow asindicated and With aver- U V gauges for automobile radiators.

The object'of'the inventionis to provide a simple and effective device especially adapted to die casting constructionbywhich the water level will be effectively registered by the float'means and also the boiling in .nitely appear from dicated by agitation ofthe .vane.

Objects pertaining to details and econo mies of construction and operationwill defithe detailed description toifollow. i i

I I accomplish the tion by the devices and means. described in the following specification. The invention is clearly defined and pointed out in the claims. I

' A structure which is a preferred embodiment of. my invention isclearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a plan view of my structure. Fig. II is a front'elevation view with the radiator cap part in vertical detail section on the'irregular line 22 of Fig. I.

Fig. III is a detail central vertical sectional view on line 33 of. Figsl and II showing details of construction.

Fig. IV is an enlarged detail sectional view on line 44 of Fig. I showingthelock means for retaining the cap. effectively in positlon.

In the drawing the sectional views are taken looking in the direction of-the little arrows at the endsof the section linesand similar numerals of reference refer to simi lar parts throughout the several views.

The parts of the drawing will be 0011-" sidered by their numbers. 1 is a radiator cap having laterally projecting ornamental arms 2. It is formed to cap over and fitupon the radiator neck 3 to which it issecured in the desired position by the set screw 3, the head of which is broken off at the time of installation. The screw is necked in awell known manner, see dottedv lines in Fig. IV, to that end. 4 isia' vertical tube tightly fitting a perforation in the said cap 1, being suitably enlarged and shouldered at 5 to insure its effective seating. A jammed lock nut 62 is screwed on the tube 4 against the inside of the cap 1.v

preferably triangular in formYwith. apex up objects of the inven overflow pipe if need be. I

To provide a proper, opening for filling Letters Patent, is: j

The dial member 6- is, in'the em odiment illustrated, provided with a relatively 9 to a float 10-atits lower end; The float 10 is disposed in achamber 11 made up of a edges of the slot and move upand down section of tube threaded onto the lower end of tubec. Thelower end of }tube 4 thus;

forms a limiting stop to theupward move-v ment of the float 10. The -upperend of the float is in the 'form of a valve and the lower ping of the'water up to the dial. Thelower end of this tube 11 is sharpened to perforate if need' be'the deflector plate of thin sheet metal found in many automobile radiators.

, end of tube 4 is a valve seat to prevent slop- 1 By grasping the handles '2'thegchamber I ll canbe forced through; the thindeflector plate or force it to one side and' displace the the radiator without removing thecap I pror vide a cover 12 which is pivoted at 13 at one sideand retained by springfrictionball '14 at theopposite side.

The triangular form ofdialjhead-is' of.

advantage in that while it'presentsja neat appearance it is of such form? as notto be I,

readily injured and isvery staunch.

I have described the improvedindicator inits preferred form. I However, I desire to state that it may be varied] considerably without departing from my invention.

Having thusdescribed my invention,

whatI claim'as new and desire to'secure by therein and also having a filling opening at center of the cap,- adial memberprov-ided with an integral tubular shank. disposed l through'said hole in said cap and secured therein, said dial member comprising a tri-,
